COMPOSITION FUEL.

speciaeation of Letters Patent. Patented June 25, 1918.

Application led May 1, 1916. Serial No. 94,545.

To all whom it may concern:

Be it known that I, SAMUEL LRosE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain n ew and useful Improvements in Composition Fuel, of which the following is a specn'ica- Y tion.

The invention consists of a chemicallytreated combustible substance adapted to be used as a fuel and heating agent, particularly in portable devices having an open re boX or chamber in which the fuel may be placed and consumed and the heat conveyed by radiation through the walls thereof. Preferably, the fuel is made in the form of a cake or disk, either round or angular sided and.' of any desired size according to its place of use, and the fuel possesses the property ofbeing readily ignited by a match and of 1mpartmg a quick com' ustion without an objectionable amount of flame, smoke, smell or gases.

In the accompanying drawings, Figure l is a perspective view of a rectangular cake of my improved fuel, and Fig. 2 a perspective view of a round disk of the same substance. Fig. 3 is a plan view of a rubber vulcanizing device adapted to use the fuel in the form shown in Fig. l, and Fig. 4 is a plan view of a Vcircular vulcanizer adapted to use the round combustible disk. Figs. 5 and 6 are sectional and side views respectively, of the vulcanizing device shown in Fig.' 3, showing they fuel in place in the combustion chamber thereof.

The fuel consists of a liat cake or disk 2 made of straw-board, card-board, or equivalent combustible material of any suitable thickness adapted to provide a body or base which may be impregnated throughout with a chemical solution to promote` combustion and hot embers. This solution consists of four parts of nitrate of sodium, one part of chlorid of sodium, and eight parts of water. Followin thorough saturation of the cakes or disks m this solution, the excess solution redetermined degree of heat by is removed by subjecting the cakes or disks to pressure. Then the pressed cakes are placed in pans and dried 1n a suitable oven.

iThe dried and compressed roduct is tough 'and stili and not easily roken; is readily ignited by a match, and burns quickly if provided with suliicient air, leaving a body of glowing ashes or embers to impart heat after vthe :(iare.

Obviously this combustible may be used wherever it may be found to have utility.- For example, it may be employed as a heating agent in the vulcanizing apparatus shown in Figs. 3 to 6, a device known to me, comprising a vulcanizing body 4 and a base member 6 detachably connected thereto by clamping screws 8. The rubber article to be vulcanized is placed between the base 6 and the bottom face of the body 4, while the vulcanizable material for effecting the repairs is centered at the shallow concavity 10 in said bottom face beneath the center of the heating element 2 which rests in the open shallow chamber l2 in body 4. The chlorid of sodium is employed to slow combustion and more or less may be used as compared with the proportion stated.

What l claim is:

l. A composition fuel consisting solely of a carboniferous material impregnated with nitrate of sodium and chlorid of sodium.

2. A composition fuel consistin wholly of a compressed cake of straw-boar impregnated with nitrate of sodium and a small percentage of chlorid of sodium.

3. A composition fuel consisting of a compressed cake of straw-board treated with a solution of four parts of nitrate of Sodium and one part of chlorid of sodium and eight parts of water. Y

In testimony whereof I aiiiX my signature in presence of two witnesses.
